Abstract
The present invention relates to a touch panel, which includes a first input layer and a second input layer superposed under the first input layer. The second input layer includes four vertexes, a net circuit, and a switching control circuit. The net circuit also includes two input ports. The two input ports are connected to the four vertexes via the switching control circuit. When the first input layer is touched, the two input ports are loaded different voltages respectively. Through the controlling of the switching control circuit, during the preceding half time of touching process, the electric potential of the first vertex is equal to that of the forth vertex, and the electric potential of the second vertex is equal to that of the third vertex; during the rear half time of touching process, the electric potential of the first vertex is equal to that of the second vertex, and the electric potential of the third vertex is equal to that of the forth vertex.
